First, safer sexy, every time. This includes "topping." Giving blow jobs does have a measurable, if small, risk of HIV infection.
Second, managing the number of sexual partners. It's just like lotto. The more tickets you buy, the more likely you are to "win." If you seek out places like sex clubs and hook up a lot on line, you are probably meeting people who do the same....and when you sleep with one person, you are sleeping with their full sexual history.
Third, avoid behaviors that make you take chances: drugs and alcohol.
Those are real steps that will help you.
